How To Jailbreak iPhone 4, iPhone 3GS Using Limera1n [Windows]


Geohot surprised everyone by releasing limera1n yesterday, a day before the release of greenpois0n by the Chronic Dev Team.

Limera1n can jailbreak iPhone 3GS, iPhone 4iPad, iPod Touch 3G  and the new iPod Touch 4G.

In this guide, we will take you through the step by step procedure to jailbreak iPhone 4 and iPhone 3GS.

Here are some important points to note before you proceed.

  • This guide is only for iPhone 4 and iPhone 3GS users. iPod Touch 3G and iPod Touch 4G users can use this step by step guide to jailbreak their iPhone using limera1niPhone 3G and iPod Touch 2G users can use Redsn0w to jailbreak their iPod Touch.
  • Please note that jailbreaking your iPhone may void your warranty and hence proceed with caution.
  • Do not forget to backup your iPhone before you proceed. You can refer to this post for instructions on how to backup your iPhone.

  • Limera1n supports iOS 4, iOS 4.0.1, iOS 4.0.2 and iOS 4.1.

  • Limera1n is currently available for Windows, Geohot plans to release the Mac and Linux versions of limera1n soon.

  • Please do NOT upgrade to iOS 4.1 if you want to unlock your iPhone. You should wait for iPhone Dev Team to release PwnageTool.

  • Limera1n does NOT hactivate your iPhone, so your iPhone should be activated via iTunes first.

  • After the jailbreaking process is complete, do not forget to checkout our article on tips to keep your iPhone secure.

  • Please ensure you are running iTunes 9.2 or later.

Step 1: Download the latest version of limera1n from this link and save the application on your desktop.

Step 2: Double click on the limera1n exe to launch the application.

Step 3: Please ensure that your iPhone is connected to the computer.

Step 4: Click on the "make it rain” button.


Step 5: You will see that limera1n puts your iPhone in recovery mode. Immediately after this, follow the instructions.


Step 6: Limera1n will be prompt you to press both the home and power buttons.


Step 7: Limera1n will be then prompt you to release the Power button. Continue to press the home button.


Step 8: You will see that limera1n has put your iPhone in DFU mode. Continue to press the home button.


Step 9: While limera1n performs the exploit, you will see the limera1n logo on your iPhone.


Step 10: When limera1n has successfully jailbroken your iPhone, you will see β€œdone” and get the following message.


Step 11: You need to restart your iPhone. You will notice that there is a new app called limera1n installed on your iPhone.


Step 12: Launch the limera1n app to install Cydia on your iPhone. Select Cydia and tap on the Install button to download and install it.


Step 13: After Cydia has been installed, reboot your iPhone.


Step 14: You should find Cydia on your iPhone’s homescreen. You can launch the limera1n app to uninstall it as it is no longer required.


Hope this helped. Please don't forget to drop us a line to tell us how it goes.

    Your the MAN! I wish I could JB but I'm going to Korea for 12 months and need to unlock it so I can use it there. So atleast o now know I can JB.

  • hxclos

    You can't get anymore clearer directions than that. Thanks.

  • Joe

    This is great, thanks for putting this together. Now, I have a question. I have and iPhone 4, 4.0.1, jailbroken with My SHSH blobs have been saved to Cydia for 4.1, confirmed by TinyUmbrella.

    What do I need to do to get 4.1 jailbreak? I really don't want to lose anything.

  • good

  • Nicofeine

    Thanks Geohot! & to all Devs whos working hard for this. Hopefully 1 of you guys makes an unlock for us stuck on basband 5.14.02 soon.

  • Joe

    Do I need to update to 4.1, preserving my baseband, then use limera1n? Or, is there an option of using a cooked .ipsw?

  • excellent !!….thanks.
    got another phone with new modem firmware, just waiting for downgrade tool and i and a few thousand others will be other the moon !!…great job

  • Luis

    Can I back up a limera1n JB 3GS 4.1 to a non broken state.
    Than JB with greenpois0n for unlocking reasons? Or is there an easier way?

    Or will there be a way to unlock it while it's JB later?

  • Kobe

    Geo is the man once again!!!!

  • Yoga Sugiharta ( BALI )

    Thank you it's working. GBU. I am using iPhone 3Gs ios 4.1. I am still waiting for unlocking. Thanks GEOHOT.

  • Ohkami

    Works fine until step 8 but then the limera1n logo that's supposed to show up on the iPhone in step 9 never does. Just Apple logo appears on iPhone and limera1n application enters step 10, announcing the phone was successfully jailbroken. Which actually it wasn't, there is no limera1n app on the iPhone, also not after restart.
    Environment: Win XP in Parallels 5 VM on Macbook Pro OS 10.6, iPhone 4 running 4.1

    • Adam lewis usa

      Yea same thing here have you found a solution yet by any chance?

    • bev

      Yeah, me too – same situation. iPhone 4, ios 4.0.2, bb 01.59.00. This worked before – I used to have a Limera1n icon and a Cydia icon on this phone, before I restored it (using signed custom IPSW created with Sn0wbreeze). Any ideas for why this might not be loading properly?

      • bev

        Miracle! It worked! I just rebooted and (after Windows performed SIXTEEN updates for me), restarted my phone, and tried again – it worked like a charm. πŸ™‚ THANK YOU for the very detailed directions!

  • Kbih

    I can successfully jailbreak my 3GS on 4.1 (new bootrom, previously jailbroken and all..) but when I launch Cydia it's always stuck on "Reorganizing, will close when done" and no matter how many times I realaunch Cydia, restore my phone, and jailbreak it again, it doesn't help.

  • tnek

    Just installed on 3GS 32GB ver 4.1(8B117) model: MC133KN modemfirmware: 05.14.02

    Installed with NO problems πŸ™‚ great jubii, now back in buisness…

    GREAT thanks to GeoHot/ Limera1n

    best regards

  • tnek

    just backup'ed in itunes – then let it rain πŸ™‚ and after jailbreak… everything is just like before I did it πŸ™‚ super great – now we have to remember what were going to do with the jailbreaked iphone :))

  • Yo Mama

    greenpois0n has nothing to do with unlocking. Ultrasn0w is the ONLY thing that unlocks the phone currently.

  • qasim

    heloo everyone
    i successfully Jb my iphone 4 . My SHSH blobs have been saved to Cydia for 4.1, confirmed by TinyUmbrella. I can not install cydia because is banned in china. when i open limeran1 then it say check your internet connection. Can ayone help me?Any way to use proxy to install cydia on iphone?

  • Yo Mama

    Wait for the MAC version, or use a windows PC. Your problem is probably XP in the VM.

    Nobody using 64bit Win7 has had problems as far as I can tell (except for 3gs new boot rom)

  • mazri

    Hey guys it werks for my iphone3gs firmware 4.1. wohoo… Thanks goehot!!

  • lemonra1n

    in reply to Yo Mama in reply to Ohkami…
    What is with blogger conjecture and lack of fact??

    "Your problem is probably XP in the VM. Nobody using 64bit Win7 has had problems as far as I can tell"

    I have the same issue as Ohkami, iPhone 4 4.1 clean restore on a win32 xp machine, win64 xp machine, win7 64 machine, macbook pro running xp32,xp64 and win7 64.

    BARNEY… IT IS NOT AN OS ISSUE is there anyone that has something knowledgeable to add? other than "wait till it comes out on mac"

  • Nick

    i ve got an iphone with FW4.01 JBed using do i update to 4.1 the let it rain or does limerain install 4.1 ??

  • luis casas

    Worked GREAT on 3GS 4.1(8B117) model: MB717ll
    05.14.02 cant wait for the Unlock.

    AWSOME JOB….i had to donate thanks again your a saint!

  • Emmanuel

    install 4.1 first. Be sure you don't need carrier unlock, cause 4.1 overwrites the baseband and no unlock is available at present time.

  • spiz

    I didn't understand one thing, I have an iPhone 4 with iOS 4.0.2 can I use limera1n to jailbreak it? I need the unlock so i don't want to upgrade to 4.1. Is apple still signing 4.0.2?

  • slim

    worked for me iphone4 4.1,but how will i unlock please

  • Aly

    Had it working on the iPhone 4 factory unlocked 4.1 brilliantly, The limera1n icon did not appear because i turned my phone off before clicking on make it rain but worked the second time around when I left it on.
    Also there were some posts that installous is not working after limera1n on cydia which is not true, it worked perfectly fine and I am enjoying my iPhone 4 to the fullest with a jailbreak and installous, ooh I also did not loose any application or any contacts or messages, everythin was exactly the same..
    welcome back GEOHOT with a massive Bang.. !!

  • adam

    geohot has pissed a few ppl off by releasing this jb. its not even ready unlike the greenpois0n which has gone through loads of testing.

  • dee

    how old is the guy 10! this guy geo is such a damn attention fiend douch bag!!now that he release is damn tool shatter is not goin to release thier powerful tool!!! he jeopardize for people who waited for shatter to drop! out of the fuckin blue he decided to release it on the sameday.he bowed out saying he wasnt goin to do it no more because of the pressure he was receiving -obviously he likes it! I want to still unlock my damn phone so I'll stay from this out of the blue buggy jb tool.

  • Confused

    So if you want to unlock you should wait? What if my iPhone is already 4.1
    ? Will I still be able to unlock? Can I use this jailbreak or should I still wait?

  • Ipodtouchuser

    Has anyone tried this on iPod Touch MC model? If so please let me know if it works. Thank you.

  • JBforME

    Run Limera1n as Admin

    Had to reboot in between installing both Limera1n and Cydia. Works like a charm.

    Finally we get Winterboard on our iPhone 4's with 4.1 pre-installed

    Hate the politics of the game, but thanks Geohot, you truly are the best.

  • Ipodtouchuser

    Once u r on 4.1 u can't unlock until they release the 4.1 unlock so just jailbreak there's nothing else you can do

    any help i have a 32gb iphone and i ran limera1n on windows 7

  • Jr

    Stupid even if they release Greenpois0n u can not unlock your phone if u upgrade to 4.1 from iTunes. Greenpois0n is just for jailbreaking and same for limera1n.. Do you even know what you talking about or what your doing? I jailbreak my iPhone 3GS, iPhone 4 save my baseband to tiny umbrella and it's unlocked with software 4.1 it's not buggy.

  • use tiny u b to restore make sure tss is runing restore to 41 it wont update B B only on iphone 4

  • Ali


    Thanx Limera1n, jb 3gs 4.1 5.14.2 MC model successfully.

    For some people this doesnt work because they forget to let go of home button when it "dfu mode wait" comes up.

    please some1 answer this
    on this device its first time jb nw, because shsh exists on cydia now, can i downgrade to 4.0.1 and then jb via jailbreakme followed by unlock via repo666

    thanks in advance

  • did u restart after J B?

  • Pyrce Czech

    iPhone 4-16G, iOS4.1(8B117), Firmware 02.10.04. (no need for unlock).

    Works perfectly.

  • YES


  • jackie

    it did not jb for me instead it started my phone at itunes. loced me out

  • dee

    listen dick-greenpoison and shatter is a jailbreak for life and is basically intended for the devices with the new apple a4 processors,for people who have those devices like myselfyes I do know what I'm talkin bout I wanna a jailbreak for life not temporarily and it was a douce bag move for him to release it the sometime dev-team did alot of work towards this and if u read there blog they are not happy bout limerain either.

  • Mickey13172

    Works like a charm on iPhone 4 4.1 firmware..install cydia and reboot..doesn't get much easier than that compared to the old days πŸ™‚

  • midian

    works like a champ. iphone 4 ios 4.1. no issues at all took less than 5 min.

  • Abdulla

    Geohot is the BEST!

  • Dre

  • Joe

    If you find an answer to this, please reply. I asked the same question above. I wish the moderator would help us out. I doubt we are the only 2 people that have this situation.

  • Jennifer Eksund

    Like a Charm!! thanks! 3GS on 4.1… instructions clear and straightforward…

  • dravenb4u

    Geohot.. U R The Man as stated above.. Could not be any easier… Brand new iPhone 4 with 4.1 pre-installed (just got a little over a week ago).. Following the instructions above worked perfect first time. As stated, had to reboot to see Cydia…

    Now I can get my SBSettings back..

    Thanks for the tutorial above to guys.. awesome work… now to do a donate to GEOHOT…

  • Sofa_Cue

    Cydia doesnt install tried it many times and reran the jail break, IPhone 4 on 4.1. Any ideas?
    Imediately after JB insatlls phone turns off by itself and Limera icon is there, launch it to download and install cydia all looks well except after reeboot no icon.

  • Jordan

    Why don't we just thank Geohot for releasing the tool and them work out their differences – the community has their jailbreak just be grateful

  • dravenb4u

    now to try my old 3GS.. Can finally update to 4.1 on that one… wife will be happy…

  • amwat

    thanks geohot and CDV for limerain and greenpoison
    for people whi have problem with limerain on iphone 3gs or iphone 4 maybe… i had enough jailbreaking my iphone with no success (more than 100 times) finally i figured out the problem was coming from itunes 10 i downgraded to itune 9.2.2 and i succefully jailbreak my iphone from the first time please try and let me know

  • Adam

    From the UK! Worked first time on iphone 3gs on 4.0.2 and new bootrom. Cydia installed straight away
    Then used ultrasn0w to unlock the phone (baseband 5.13.04) on to all networks!

  • If only that fame-hungry geo wasnt so impatient to release his damn L1mera, i wouldnt be misled and would safely preserve the baseband with Chronic guys' Pwnge tool. And now, even though I can jailbreak I still lack unlock !!! Damn you Geohot, you need to learn how to work in a team ! What am i gonna do with 02.10.04 baseband now? Does anyone know if there is smth coming out for the unlockers?

  • dravenb4u

    Hold down the power button, slide to turn off.. After black, turn back on, Cydia should be there.. Let us know how you make out

  • Adam

    ps thanks to geohot!

  • dravenb4u

    dude.. didn't you read the instructions? It said wait for pwnage if you need an unlock. It could not be more clear. Stop ragging on the guy… restore and wait for Chronic to release their fix if you feel that works better. No harm done. You did backup first right????

  • rami

    thx amwat you rock man ….uoupiiiiiiiiiii

  • kormakid


  • i was able to jailbreak my iphone 4 with limerain without a problem thanks now i want to unlock it so release something asap

  • Grandlarceny

    Two questions
    1. I used tinyunbrella to keep my baseband and updated to 4.1 (iPhone 4) and jailbroke it..

    Since I did that I'm still able to unlock my phone in the future currect?

    2. Has anybody found a way to fix bitesms on 4.1 or should I just wait for the fix or update?

    Any answers would be nice

  • amwat

    yw dude πŸ˜‰ i felt the same after the 100 times unsuccessful try

  • Didnt follow instructions really well. My mistake no doubt ! All I did was shsh with tinyumbrella. But the baseband updated from 1.59.00 to 02.10.04 – and there is no way back for baseband that i am aware of… Surely for you guys who dont care about unlock, L1mera made difference – one day difference ! Geo could use his exploit later, but NO – he wanted to be the first ! And for people like me who have no time reading instructions (or not much informed) it created a problem with unlock now. The chronic dev team guys' tool would have eliminated any chance of upgrading baseband – no risk ! But geo wanted to be spotlighted first! No reason !!!

  • Poetlike

    Hi there I have 3GS new bottom and jb on windows 7 64bit no problem using limera1n Beta 3.


    No, you didn't 'Brick you Phone'. Brick means you phone is just that – a worthless brick, good only to be thrown away. You restored your phone and got back what you had.
    The update just didn't work for you, but no harm done. So try again or wait for a few more bug-fixes.

    You're unhappy? Just how much did you pay for this free tryout?

  • Joe

    I have a question for you…was your iPhone 4 already jailbroken with before you did all of this?

  • fingers21

    windows 7/iPhone 4. JB fine. I found, when the phone enters DFU mode, DO NOT let go of the home button, just keep it pressed, eventually the limerain logo appears, still keep holding until the connect to itunes reappears, then let go and restart!

    Hope this helps.

  • Sofa_Cue

    I had to do a restore, the JB, then restore from back up. All works now. Thanks everyone to invovled.

  • mazen

    yes yes i made it woooow
    i have iphone 3gs new bootrom 4.0.2 firmware 5.13.04
    i was waiting from 2months and i took my chance and i jailbreaked it and unlocked it right now thanksssssssssssssssssssssssssss alot

  • Parupkar Singh

    work perfect on iphone 3gs thanks to geohot!
    but cydia is too slow!
    anyone havin the same problem?

  • chris

    i love you…

  • Marcus

    I need an opinion. Sincere ask …
    Im from Malaysia, and i had my iPhone 4, iOS 4.1.
    Im using Windows XP and i had limera1n. Just predict as in imagination. I doubt that i able to JB but as if accidentally it locked carrier, is there anyway to unlock it?

  • Josh

    limera1n does not install 4.1… you must update through itunes then jailbreak with limera1n, however if you are looking to unlock dont upgrade to 4.1 until pwnagetool is released since itunes upgrade will also update your baseband which currently cannot be unlocked

  • me

    how do u get rid of the limerain icon.

  • Grandlarceny

    Srry I forgot to metion that.
    Yes it was jailbrocken with
    And my iPhone is from release as well if that helps.

  • Abdulla

    it is your mistake! you're the one who was impatient to upgrade your iphone. if you don't like geohot, you shouldn't have used his jailbreaking too from the first place.

  • Abdulla


  • Thanks, we have update the guide with that tip!

  • yankz23

    is this tethered or untethered jailbreak ?

  • PeteGall

    I think you are right about the iTunes thing, I tried terminating it's process, and then JB, with no success. I then went into safe mode to try it (since the iTunes software and drivers wouldn't load) But this prevented the JB software from detecting the phone also.

    So finally I rebooted as normal, and I though, maybe I can JB my phone before the computer fully boots up its software. So I typed my name and password, and as soon as my desktop popped up, I plugged in my 3gs, and clicked the limera1n icon, and followed the instructions as normal… Tada! It worked πŸ™‚

    So thanks for the idea, I tried it this way cos I didn't want to tamper with iTunes as my backup was on there

    And thanks to the developers for there hard work on this exploit :-*

  • Its untethered

  • Wiszam

    worked just fine for me

    iphone 3gs ios 4.0.2

  • Grandlarceny


  • j

    Does this work with 3g?

  • Joe

    Thanks for the info. From what I understand, yes, you should be able to preserve your unlock because the baseband wasn't updated. Tiny Umbrella is your friend. πŸ™‚

    So…one more question, please. Is this what you did?

    1. Start Tiny Umbrella
    2. Once the phone is recognized, click Start TSS Server.
    3. Then, open iTunes. Hold down the "Shift" key, then click "Restore". This will allow you to choose your specific .ipsw file. *Where did you download your iPhone 4, 4.1 .ipsw file*
    4. iTunes updates your iPhone to 4.1

    5. You download limera1n, then make it ra1n.
    6. Reboot the iPhone, then install Cydia from the limera1n icon on the iPhone.
    7. Reboot once more just for good measure.

    Are these the steps you followed? Also, did you already purchase any apps from Cydia? If so, did you have them once you upgraded to 4.1?

    Sorry for all of the questions. I want to make sure I have this right before I try it. I really appreciate your help!

  • AC

    iPhone 4 4.0.2

    I haven't tried JBing it yet, is there a way to unlock it yet?

  • MadMan

    Are you stupid or what ?
    You updated baseband. It has nothing to do with limera1n. You should have updated to 4.1 without updating baseband. There are tools for that. People like you make me mad. How dare you to blame anybody for your stupidity !!!

  • MoronHater

    No that's not it. Geo released because his worked on all devices, Chronic's worked only on A4 processors devices. Geo's point was that the exploit originally planned for GreenPoision should be saved for later since it doesn't work with every device. All of Apples iOS devices going forward will have an A4 proc, so save it.

    Stop ragging on Geohot when your problem is all between chair and keyboard.

  • cmonkey

    Worked well… It took a couple of tries but it was my fault, I didn't have itunes on so I didn't get the limera1n logo. Finally read all the comments and got it working.


  • A Rivera

    limera1n was able to install on my 3gs. I now got Cydia on my iPhone (YAY!). Will post some more when I get done playing around with available apps on Cydia. THANX Geohot!!!

  • natim

    Lost Carrier: after using tiny umbrella to save baseband then using limera1n for JB my previously jailbroken iphone 4 which was on ios 4.02 all appeared fine, jb seemed to work even restored all apps using pkgbackup. I then noticed I had no carrier and couldn't get it back. Out of desperation talked to ATT they suggested bad sim which didn't seem right to me, what's odds of sim going bad during a JB? So i went and got new sim from ATT store and same thing no carrier. Wifi works no problem, anyone have ideas or experienced the carrier loss?

  • jose vergara

    Go Development Team and geo once my phone unlocks i will donate to both hackers cuz you guys made cydia happen over the past years so congrats u have my word both hackers ill be donating confirmed 4.1 on 3gs newbootrom jailbroken and lets make some peace between everybody keep up the great work

  • Since you used Tiny Umbrella, the baseband is probably preserved. So try to install Ultrasn0w from Cydia to unlock your iPhone:

  • OPS

    was trying out the overall process.. upon completion, after uninstalling limera1n – several probs on my part;
    i) realised the cydia icon is gone.. tried restarting, ii) then the email icon image goes blank albeit still usable,
    iii) and the app store icon is completely gone..

    please advise..
    ~ to redo the whole jailbreak process again? OR…

  • chipsamoy25

    After limera1n jailbreak is done to my iPhone 4 iOS 4.1, will I be able to ever restore my iPhone or update to newer operating systems?

  • helpme

    hi guys..

    pls help. I applied the JB on my 3GS missing the step to upgrade to OS 4.1 first. Now my phone after reboot hangs at the apple logo. Is that anything i can do to save the phone?

    thanks a lot

  • Roth

    I dont know if this happend to anyone else, but APTBACKUP caused all of my Itunes apps to dissapear and caused itunes to see everything as "other" had to do a restore. then while rejailbreaking itunes popped up, i had used my Right hand to hold the buttons and couldnt move itnues out of the way so i didnt know when to let go of power, held it too long and now it wont rejailbreak it just freezes on let go of power each time i run it.

  • Roth

    now im stuck in dfu mode and my thumb hurts


    I bought my 3GS in October of 2009 through Rogers, which is my carrier. I do not need to unlock my device.

    my versions are iOS 3.1.2(7D11) with Rogers 5.0, Modem firmware is 05.11.07.

    To upgrade to iOS 4.1 and jailbreak my device, can I simply update through iTunes and then download the above limera1n, and jailbreak my device or would I need to make a new ispw and so on?

  • kaan

    well..thnx for the person who release this limerain so happy and he deserved my donation …i was waitng for this ..thnx ..

  • JohnnyPistolero

    I keep trying to jb my iphone 4 with the 4.1 firmware and i keep having the same problem. I follow the steps exactly but i never see the limera1n logo. When it says its done jailbreakin all i see is the apple logo and my phone is just the way it was before i tried jailbreaking… any idea?

  • Kk

    Jenn, how did you upgrade to 4.1 without upgrading the baseband? I have a 3gs, old bootrom, on 3.1.2. Thanks in advance

    Thank you for this update. I have 32GB 3GS with iOS 3.0.1 running. I want to upgrade to 4.1.
    Please help me with my query:
    Do I need to upgrade my OS from iTunes to 4.1 and then use Limera1n to jailbreak? Or shall I run Limera1n and it will give me options to upgrade 4.1?

    Thank you… and please help.

  • Maystar

    3 cheers to the Geohot team. You guys have done a great job. I have been desperately waiting to jb my 3gs on 4.0.2 and your s/w worked like charm. Many thanks for all your efforts you have put into developing this tool. Great job and keep up the good work.
    Thanks again!!

    I have an iPhone 4 with original 4.0.2, I just Jailbroke it with Limera1n, then Unlocked w/Ultrasnow from Cydia, worked perfectly with my TMobile Sim Card (Cut the TMobile Sim card down to Micro size). Just don't update to 4.1 because as of today, there is no unlock solution for 4.1. Stick with 4.0.2 and your iPhone 4 works just fine UNLOCKED.

  • calvin

    after jailbreak using this method, i am missing icons (calculator, calender and appstore) any suggestion?
    iphone 4 4.0.2

  • I think you are right about the iTunes thing, I tried terminating it's process, and then JB, with no success. I then went into safe mode to try it (since the iTunes software and drivers wouldn't load) But this prevented the JB software from detecting the phone also

  • Norman

    I had same problem. Tried the software, but it did not work for me.

    Thought it may have something to do with using a different SIM to unlock, so found the following, tried it and it did not work as described but somehow it opened up my 3G service:
    3G was on, then remove the SIM
    Use wifi to reinstall ultrasn0w (got an error when trying this, something to the tune that it could not connect to the repo666 server)
    Restart springboard
    Put SIM back in
    And mysteriously the 3G data services started working.
    The original post did indicate that you would have to do this every time you reboot your device, I have not tried it πŸ™‚

  • wander

    I live in brazil and I could JB my iPhone3GS perfectly.

  • Ray

    I am running 4.1 on my iphone 3GS and use a MACBOOK with itunes 10.0.1. Can I jailbreak using Limera1n yet or do I have to wait for another version to release specific to MAC?

  • Cpehc21

    I dont understand the last step (You should find Cydia on your iPhone’s homescreen. You can launch the limera1n app to uninstall it as it is no longer required). Do i delete limra1n or cydia? Other than this everything went awesome only had to retry once.

  • You can uninstall limera1n after you have successfully jailbroken your iPhone.

  • 34yroldmanwithiphone4

    counting to ten is crucial!

  • 34yroldmanwithiphone4

    for me, i just leave limera1n. no harm no foul empty space saved though?

  • 34yroldmanwithiphone4

    i would re set and try again. i am doing ok on my iphone 4 same with wifes 3gs and daughters ipod touch 4. i think its just an install issue of some sort?

  • Haley Storms

    How long does it take for the DFU mode to be done? mines been there for about 2 hours now??

  • Rob I

    this is awesome! worked on my iPhone 4 4.0.2 then downloaded ultrasn0w to unlock! i was about to return my iphone since i read about factory 4.0.2 cannot be jb or unlocked yet, then BAM! here comes limera1n!!!


  • Mike

    Hello Guys,

    I need HELP with something before I do this, please read and answer me the right answer πŸ™‚

    I just got an iPhone 4 from the UK and Its locked, 4.1, now before I do anything stupid I want to know if this method works on it or not, its on the new baseband and i'm a bit savvy when it comes to this unlocking and jailbreaking, so will it screw my phone or not, and what is the worst thing can happen to it if I messed up ?

  • Jane

    My iphone 3gs already JB, but y i unlocked my sim already my phone still appears no network coverage???? how to slove it???

  • iam mato

    hi… i tried also your "after login quikly run jailbreak program tactic" and it didnt give me also any luck… now im really really frustrated…

  • Danny

    For me exactly the same issue. I am using iTune 10 on windows 7, and my iphone 3GS is running iOS 4.1. (Never jailbreaked)

    In step 7 of the instruction, always let me 're-try'….

    I only can restore my iphone as a new phone to use then. Otherwise it stays at recovery mode..

  • Tg

    it works thanx a lot who design it…..

    yes you can do it just try you will get unlock your phone

    please help!!!!
    I tried to jailbreak my iphone with this programm, and it didn’t worked..My phone shows Itunes logo..I cant do anythig with my phone now!!not even power off!!PLEASE HELP!!

  • Zoya

    Try a reset (hold down power button and home button until phone shuts off). If this doesn’t work its likely you will need to restore and try your jailbreak again. How long do you let it hang at the Apple logo? It can take some time to boot up the first time after a jailbreak. Another option is to just try the jailbreak process again without doing a restore.

    this is helpfull!!
